The Ride LTD Snowboard Bindings are the only offering in the lineup that have both an INFINITY™ chassis and a Slimeback™ highback. Why? Because when it comes to getting more responsive freestyle performance, most binding manufacturers typically look to a plastic chassis in order to achieve a lightweight feel -- the LTDs, however, harness the power and durability of 100% aircraft grade 6061 aluminum alloy while the smooth-flexing Slimeback™ works to maintain that fluid, flowy feel. If you're keen on a responsive yet tweakable high performance connection, then look no further. The Ride LTD Snowboard Bindings are the ones.
